CAPP: Calculating Standard Values

Hi PP Friends. This is my 1st blog ever in the SDN. In this blog im going to show an example of CAPP. Why CAPP? because i dont see for a long time a project that have this stuff, nor questions in the SDN not OSS Notes in the Marketplace. I dont know if this functionality was discontinued by SAP but its still active in ECC6, so why not post about it ?

Lets Begin!!

1. What is CAPP?

Is an alternative way to calculate standard values in PP Orders (also in Routing, but dont complicate this stuff), that allow tricky and complicated formulas.  When i was on the university, in the course “Manufacturig Process” we study some formulas for milling drilling, cutting,and this kind of things that dont follow rule of three, in spite depend on speed, density and other parameters.

2. CAPP is an old functionality, most oss about capp refer to version 3, so this stuff exist before y2k, you know that ?

3.Maths. In this example, we are going to work with 3 parameters, but you can work with more: 6, 7, 10, not sure but more. My parameters are:

+ Net Weight: is the FG Net weight in the Material Master

+ Order Quantity: is que quantity in the PP Order

+ Machine speed: is a parameter that you maintain manually at Order Creation.

Imagine in our manufacturing process we need to calculate the machine standard value with this formula:

MACHINE TIME =  (  “GROSS WEIGHT” *  “ORDER QUANTITY” )   /  “MACHINE SPEED”

There are other options to valuate patameters, eg you can read a Ztable without abap code, you can use parameters from the routing or you can write abap code in order to do whatever you want =)

4. OK, 1st check  Material ZPP_FERT_CAPP01 in plant 6000.

In the Material Master, we set field NetWeight. We are going to valuate automatically a parameter in the production order with this value.

5. Well, begin with the  Order Createion. Set 10 Units as quantity.

6. System request valuate caracteristic Machine Speed, set “9”

7. System show all the Characteristics and the final result according to the formula. Also show the “Weight Material Master come from table MARA”.

The Formula:  (33 * 10 ) / 9 = 36.667

8: System transfer the Result to the Standard Value of the Operation

Ok Thats is! This standard Value can be used in Scheduling, Capacity Planning or Costing Formulas, but i guess you know about it!

In next post i’m going to explain how to do the customizing.

Arturo!

  • Hi Arturo,

    Thanks for this valuable info. This can very well be used in my existing project.

    Can you please mail me or post the next blog on how to do the config.

    If you can mail me then please mail me at

    I would deeply appretiate your effort.

  • Hi Arturo,

    Very valuable information and triggers the thought process why this is no more used in SAP and no one talks about it? but you are right awareness is less, and more and more usage of it helps and as you said testing must be keen to understand & use this concept in projects.

  • Hello,

    In your example, you are using the ‘order quantity’ as a variable for your formula.

    When calculating the CAPP formula, is the the order quantity (10) being input manually?

    Or there is a way in the formula/origin to read the value, after it was entered the first time?

  • Arturo, Had made a note long back on the limited usage of this functionality. Based on my recent reading: Out of Characteristics and tables forming the CAPP basis, tables have a type called Matrix tables. (Finally these matrix tables lead to usage of functionalities like Rapid Planning Matrix etc used elsewhere s the end part).

      My understanding is these functionalities more probably required in automotive sector have been transformed as iPPE(integrated Product and Process Engineering) functionalities and enriched under PLM space. Just my guess.

      People working in Automotive segments should be able to help better.

    Had to google to see what the abbreviation for CAPP was for 😉 . Better to expand the abbreviation/s at least once in any document, if used)

       Somehow the posting by Ann Hustis sometime back on ECC functionalities not used properly comes to mind.

    Thanks.
